VOLIVER I). MAOGILL, OF BROOKLANDVILLE, ASSIGN OR `TO HIMSELF AND THOS.POULTNEY, OF BALTIMORE, MARYLAND.

IMPROVEMENT IN HORSESHOES.

Specification forming part of Letters Patent No. 47,242, dated April 11,1365.

To all whom it may concern:

Be it known that I, OLIvER I). MACGILL, of Brooklandville, in the countyof Baltimore and State of Maryland, have invented certain new and usefulImprovements in Horseshoes;

and I do hereby declare the following to be a full, clear, and exactdescription ofthe same, reference being had to the annexed drawings,making part of this specification, in which--l Figure l is a plan viewfrom above, showing the surface presented to the sole of the hoof. Fig.2 is a view of the under side-that surface presented to the ground. Fig.3 is a 4section on the lines a: x, Figs. 1 or 2.

Similar letters of reference indicate -correspending parts in theseveral figures.

The object of my improvement is to provide an attachment for horses7shoes which may f be readily attachedand removed, serving while on as arough shoe to prevent slipping on iceor other smooth surface, and alsoso arranged that the ice-points may be renewed as required without anyspecial manipulation of the main po'rtion of the device.

To enable others skilled in the art to which `my invention appertains tofully understand and use the same, I will proceed to describe itsconstruction and operation.

The device consists of a hinged frame consistin g of two portions, A A',united by a rivet at C, and having on their upper sides (when in use)certain iianges, D, whose edges point outwardly and embrace the thininner pe rimeter ofthe bar of the shoe E. The means by which thisexpansive and contractile action is secured is a screw, G, which bearsagainst the lugs I-I II on the heel endof the frame-pieces A A', one endof the screw bearing in a socket, and the other threaded end engagingthe screw in the other piece of the frame.

I I are holes through the plates A A', through which are passed pointedsteel plugs or ieecalks .I J, whose enlarged heads abut against thelower side of the iron shoe when in working position. These are readilyplaced, re moved, or sharpened, and afford a firm tread, as they piercethe ice on which the animal is traveling.

The apparatus has been tried with full success and ma f be readilyattached or removed,

according to the varying requirements of a changeable climate, and iscalculated to save a good deal of expense in roughing horses,

injury to their hoofs by frequent driving of nails, and, whatA isgenerally worseV than the actual cost of shoeing, the delay that attendsthe shoeing of the animals when a sudden cold spell assembles the horsesof a neighborhood at the blacksmiths shop. The foot of the anif malbeing held up, the jointed frame is par-` i tially closed, the iiangesare made to embrace the inner edge of the shoe, and the screw bei ingrotated the parts of the jointed frame are expanded and firmly clasp theshoe. It may be removed when the animal is brought to the stable, andlaid away until the exigencies of I the service or the character of theroad neces- .l i

sitates its use, and when the animal is at rest` or at pasture do notafford the means of such severe injury to other animals by kicking as isafforded by the ordinary shoe with its toe and heel calks attached toand forming a part I of the shoe. v

Having thus fully, clearly, andexactly de- 3. The method of securing thefalse shoes to the ordinary shoe by means of the flanges on theexpanding bars of the false shoe.

4. The expanding false shoe, consisting of y two parts hinged togetherand provided with the expanding screw, substantially `as described.

To the above specication of my improvement in horseshoes I have signedmy hand this 14th dayof February, 1865.
